SWA Cable Tail

[Mirez2000]

Afternoon all, I'm running a length of 16mm SWA cable around 10 meters from my basement to where a hot tub will eventually live.

I'll get a sparky in to wire both ends but I need to know how much to leave them, for example when I ran cable for sockets in the main house I left about 30cm of excess for then to work with. Having not worked with SWA before I just wanted to check its along the same lines?

Also, am I right in thinking it just needs to enter the basement and the sparky will let junction it to a regular cable for the run that back to the CU? In other words, I dont need to run the SWA back to the CU.

Cheers

It isn't possible to tell from the internet. It depends.

You must get an electrician to visit the site and tell you what will be required.

if you have a metal CU, then run SWA to that. Leave plenty of slack so the inner cores will run all the way to MCB and bars.

You'll need to leave at least 12-20 inches at either end, I agree with EFLI as it depends as it might not be a simple job.

I’d always run it back to the Consumer Unit , always better than putting a joint in it anywhere along its run , so it’s from the Hot Tub (Id leave a Metre length spare here) then back to the C/U , spare Metre here too

Thanks all, I'll take it to the CU which actually means a different route altogether so will run a conduit it instead and let the sparky do it all. Cheers for the replies

IF you have the cable to spare, leave a meter at each end and let the electrician do the end terminations/gland.

leave as much as you can, longer the better or safer you can always cut a bit, but adding a bit will prove much more expensive
